Root level Categories mix and match
 

Is there a mod or way that anyone knows were you can mix (or cross reference) root level categories.

For instance, what I'd like to do is take a root level category

Jewelery & Watches (root)
sub a
sub b
sub c

Apparel & Accessories(root)
sub a
sub b
Jewelery & Watches


So, Jewelery & Watches would be a root level cat plus be a sub of Apparel & Accessories. It be nice to be able to cross reference and mix and match root level categories

Not possible by default. You could, however, create another sub-category with the same name and add the produts to it as an additional category.
